is presumed down at sea. An automatic SOS signal is detected emanating from an aircraft-type radio with a constant carrier frequency of 4728 kHz, issuing an automatically keyed distress message, and a dozen aircraft of the Air Force, Navy and Coast Guard are sent to search from Hickam and from Guam, Midway, and Johnston Island. Poor weather and limited visibility hampers search efforts. The U.S. Navy's USS Lansing also participates in the search. The eight missing Air Force crew and one U.S. Navy man escorting a body back to the U. S. are officially declared dead on 21 January. This was the first C-124 accident since May 1962. 4 January USAF Martin NRB-57D Canberra, 53-3973, of the Wright Air Development Center, Wright-Patterson AFB, Ohio, suffers structural failure of both wings at 50,000 feet (15240 m), comes down in schoolyard at Dayton, Ohio, crew bails out. The U.S. Air Force subsequently grounds all W/RB-57D aircraft. 6 January A U.S. Navy pilot ejects from a Douglas A-4C Skyhawk shortly after departing NAS Oceana, Virginia, when the fighter-bomber catches fire. Lt. J.G. J. R. Mossman, 24, of Springfield, Pennsylvania, is alerted by his wingman that the tail is on fire just after beginning a flight to NAS Pensacola, Florida, and ejects 10 miles SE of Virginia Beach, Virginia, parachuting into the Atlantic Ocean. Wingman Lt. Henri B. Chase orbits Mossman's position until a helicopter from NAS Norfolk arrives and picks him up. The pilot is unhurt. "By coincidence, Mossman is one of three pilots who last month practiced being rescued at sea by helicopter off Virginia Beach." 10 January The Dassault Balzac V crashes on its 125th sortie, during a low-altitude hover. During a vertical descent the aircraft experienced uncontrollable divergent wing oscillations, the port wing eventually striking the ground at an acute angle with the aircraft rolling over because of the continued lift engine thrust. The loss was attributed to loss of control because the stabilising limits of the three-axis autostabilisation system's 'puffer pipes' were exceeded in roll. Although airframe damage was relatively light, the Centre D'Essai en Vol test pilot, Jacques Pinier, did not eject and died in the crash. 10 January Boeing civilian test pilot Chuck Fisher and his three man crew lose the vertical fin of Boeing B-52H Stratofortress, 61-023, in turbulence at ~ 14,000 ft. over northern New Mexico's Sangre de Christo mountains.
